Electric vehicles (EVs) are gaining popularity due to their improved performance and environmentally friendly nature. The effectiveness of EVs depends on the successful interface between their energy storage systems and propulsion motor. One of the key components of an EV is the motor converter, which converts the electrical energy stored in the battery into mechanical energy that powers the vehicle's propulsion system. The motor converter used in EV drive system is reviewed. Non- isolated...

This Paper Presents A whole New resonant twin active bridge(DAB) topology, that uses a tuned inductor-capacitor-inductor(LCL) network. As compared to ancient DAB topologies, the planned topologies significantly reduced the bridge current, lowering every physical phenomenon and alter losses and conjointly VA rating associated with the bridges. The performance of the DAB is investigated using a mathematical model at a lower place varied operational conditions. Experiment results of a model is...

In this paper, flexible ac transmission capable wind energy system is shown. Similar to Conventional WEI, between the wind turbine and the grid an inverter is connected which can regulate both active as well as reactive power transferred to the grid. In this inverter proposed here D-STACOM is provided to control the power factor of the feeder lines. This inverter system proposed here can eliminate the use of capacitor banks and Facts devices to control the power factor of the distribution line...

The current scenario of mobile application based payment processes requires web or mobile channel which can be applicable for authenticating the identity of a remote user. Most of the current activities such as online banking, online shopping, etc. are configured with mobile devices. Since the applicability of m-commerce included various financial transactions along with personal details sharing, therefore, the vulnerability of performing attacks and threats by users have increased. The current...

Wireless Sensor Networking is one of the most important technologies that have different applications. The security of wireless sensor networks is a big concern. Hence for secure communication it is important to detect and prevent the attacks in network. Major focus is given on security and on detection and prevention of attacks. Adversary can create gray-hole attack and black-hole attack simultaneously. There are many methods which do not provide proper method to defend against these kinds of...

A Novel Energy-efficient Min-max Optimization (NEMO) is proposed to improve the data delivery performance and provide security in WSN. The NEMO scheme is applied in the virtual grid environment to periodically collect the data from source node to the mobile sink through the cell headers. Here the movement of sink is in controlled fashion and collects the data from the border line cell headers. For efficient data delivery Fruit Fly Optimization (FFO) algorithm is applied here to find the best...

The multilevel converters are increasingly becoming popular because of its high power applications. This research paper describes about the new structure that can produce increased number of output voltage waveform using a single source and reduced number of power electronic components. In designing a multilevel converter, the power electronic switches play a very imperative role as it describes the installation area, cost, configuration complexity and may more things that play a significant...

The generation of electricity using wind power is significantly increasing and has received considerable attention in recent years. One important problem with the induction generator based wind farms is that they are vulnerable to voltage disturbances and short circuit faults. Any such disturbance may cause wind farm outages. Since wind power contribution is in considerable percentage, such outages may lead to power system stability issues and also violate the grid code requirements. Thus,...

Now a day’s many of the things get controlled automatically. Everything is getting controlled using the mechanical or the automated systems. In every field machines are doing the human works. But still some area is controlled manually. For example traffic controls, road control, parking controlling. Keeping these things in mind we are trying to develop the project to automate the traffic tracking for the square. To make any project more useful and acceptable by any organization we need to...

In this project we are going to compare the performance of different adders implemented to the multipliers based on area and time needed for calculation. The CLAA based multiplier uses the delay time of 99ns for performing multiplication operation where as in CSLA based multiplier also uses nearly the same delay time for multiplication operation. But the area needed for CLAA multiplier is reduced to 31 % by the CSLA based multiplier to complete the multiplication operation.

This paper presents a theoretical result in the context of realizing high-speed hardware for parallel CRC checksums. Starting from the serial implementation widely reported in the literature, we have identified a recursive formula from the degree of the polynomial generator. Last, we from which our parallel implementation is derived. In comparison with previous works, the new scheme is faster and more compact and is independent of the technology used in its realization. In our solution, the...

This paper presents a methodology for multiple distributed generator (DG) placement in primary distribution network for loss reduction. Optimal location for distributed generator (DG) is selected by Analytical expressions and the optimal DG size calculated by IA method and loss sensitivity factor (LSF). These two methods are tested on two test systems 33-bus and 69-bus radial distribution systems. The final results showed that LSF gives same loss reduction and minimum voltage in the system with...

Conventional voltage mode control only offers limited performance for LLC series resonant DC-to-DC converters experiencing wide variations in operational conditions. When the existing voltage mode control is employed, the closed-loop performance of the converter is directly affected by unavoidable changes in power stage dynamics. Thus, a specific control design optimized at one particular operating point could become unacceptable when the operational condition is varied. This paper presents a...

The voltage sag compensator, based on a series-connected voltage-source inverter, is among the most cost-effective solution against voltage sags. When voltage sags happen, the transformers, which are often installed in front of critical loads for electrical isolation, are exposed to the disfigured voltages and a dc offset will occur in its flux linkage. In this paper, a new topology of series-connected compensator is presented to mitigate long duration deep sags, and the compensation ability is...
